E81T5-B2VC Low Alloy Steel Flux Cored Wire

Send Message Request a Quote

The E81T5-B2VC low alloy steel flux cored wire is formulated with basic type slag system. This CO2 welding wire requires 200-300℃ preheat for perfect welds. Moreover, this flux cored wire model generates stable arc, low spatter and absorbing finish.

This gas shielded wire remains excellent weldability and mechanical properties in welding of low alloy steel such as 12CrMoV at temperature lower than 540℃.
